Hello there, I'm trying to make this work but I don't get it.
If user is logged in I get a form dropdown of the posts the user has published. If it has no posts I get the message "You have no posts". And if user is not logged in a link to log in prints.
I don't get it to work with the second part "You have no posts"
What am I doing wrong? Thanks. | Let's start with proper indenting your code:
```
<select name="select-city" onchange="location = this.value;">
<option value="">Select a post to read</option>
<?php
if ( is_user_logged_in() ):
global $current_user;
wp_get_current_user();
$author_query = array('posts_per_page' => '-1','author' => $current_user->ID);
$author_posts = new WP_Query($author_query);
$numposts = count_user_posts( $user_id ); // <- you can't use $count_user_posts also - it's a function, not a variable
while ( $author_posts->have_posts() ) :
$author_posts->the_post();
?>
<option value="<?php the_permalink(); ?>"><?php the_title(); ?></option>
<?php
elseif ($numposts == 0) : // <- here's the problem - there is an elseif, but there was no if earlier
echo 'You have no posts';
?>
<?php endwhile; // <- and here is another problem, because you use endwhile in elseif, but there was no while in that elseif...
else :
echo '<a href="https://www.mysiteeeee.com/wp-login.php" >Log in</a>';
endif; ?>
```
As you can see there clearly is something wrong with that code, because you can't indent it.
So how should that look? It's hard to be certain, but... I'm pretty sure it should be something like this:
```
<?php if ( is_user_logged_in() ): ?>
<?php
global $current_user;
wp_get_current_user();
$author_query = array('posts_per_page' => '-1','author' => $current_user->ID);
$author_posts = new WP_Query($author_query);
$numposts = count_user_posts( $user_id );
if ( $numposts ) : // if there are posts, then show <select>
?>
<select name="select-city" onchange="location = this.value;">
<option value="">Select a post to read</option>
<?php while ( $author_posts->have_posts() ) : $author_posts->the_post(); ?>
<option value="<?php the_permalink(); ?>"><?php the_title(); ?></option>
<?php endwhile; ?>
</select>
<?php else : // if there are no posts ?>
You have no posts
<?php endif; ?>
<?php else : // you can't show links inside of select, so this is elseif for ( is_user_logged_in() ?>
<a href="https://www.mysiteeeee.com/wp-login.php" >Log in</a>
<?php endif; ?>

I have tried to get articles from filtering with specific KEYWORD in wordpress blog but I am not able to get. What can be the URL.
I am very much newbie to wordpress. | You can modify the list of posts displayed in feed using [`pre_get_posts`](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) action. And to target only feeds, you can use [`is_feed`](https://codex.wordpress.org/Function_Reference/is_feed) conditional tag.
So such code can look like this:
```
add_action( 'pre_get_posts', function ( $query ) {
if ( ! is_admin() && is_feed() && $query->is_main_query() ) {
if ( isset($_GET['q']) && trim($_GET['q']) ) {
$query->set( 's', trim($_GET['q']) );
}
}
} );
```
This way you can go to `example.com/feed/?q=KEYWORD` and you'll get filtered feed (be careful - most browsers are caching feeds, so you'll have to force them to refresh it). |

To give you some context, I'm using [ACF blocks for Gutenberg](https://www.advancedcustomfields.com/blog/acf-5-8-introducing-acf-blocks-for-gutenberg/), and need to find a reference for `'icon'`.
```
add_action('acf/init', 'my_acf_init');

'render_callback' => 'my_acf_block_render_callback',
'category' => 'formatting',

'keywords' => array( 'testimonial', 'quote' ),
));
}

Thanks & Regards! | Thanks @kuchenundkakao for pointing me into the right direction. I'm still answering my own question as I want to give some more context for others that may stumble upon this.
So, there are several ways to load your custom blocks, mainly:
* `add_action('enqueue_block_assets','xy_function')` / `add_action('enqueue_block_editor_assets','xy_function')`, which at the
moment is the default when creating a block with
"create\_guten\_block". This is what I was using. It might change, see
<https://github.com/ahmadawais/create-guten-block/issues/21>
* `register_block_type` as per the handbook, see <https://wordpress.org/gutenberg/handbook/designers-developers/developers/tutorials/block-tutorial/writing-your-first-block-type/#enqueuing-block-scripts>
While registering the block in PHP (like described in the handbook) is the default method and future proof, the `enqueue_block_assets` variant can load multiple blocks without the need to split your blocks into seperate files and define them again in PHP. "create\_guten\_block" for example merges any number of blocks into three files by default (blocks.build.js, blocks.editor.build.css and block.style.build.css).
Both ways do **not** conditionally load styles (yet).
When using the create\_guten\_block method, `enqueue_block_assets`, and only having a single block defined (or set up to split the files per block), the conditional loading can be added using `has_block`:
```
function my_awesome_blocks_cgb_block_assets() {
if (is_singular()) {
$id = get_the_ID();
if (has_block('my-awesome/block-type', $id)) {
wp_enqueue_style(
'my-awesome_blocks-cgb-style-css',
plugins_url( 'blocks/dist/blocks.style.build.css', __FILE__ ),
);
}
}
}
add_action( 'enqueue_block_assets', 'my_awesome_blocks_cgb_block_assets' );
```
You can combine register and conditional loading by leaving out the style / script parts in the register and load the according fontend files with enqueue\_block\_assets as in the code above.
The future proof method will be using `register_block_type`, as the `script` and `style` fields of it will most likely be used if conditional loading is ever implemented natively (see comment [here](https://github.com/WordPress/gutenberg/issues/11231)). |

328,685 | <p>On the taxonomy-{name}.php template for my "Organisation" taxonomy, I am currently showing a limited number of posts, grouped for each term of taxonomy "Format".</p>
<p>Where the number of available posts exceeds that which is displayable, I now want to enable AJAX-based loading of more posts.</p>
<p>I have followed countless tutorials and StackExchange questions on this topic, but something is still not clicking. For example, I implemented <a href="https://rudrastyh.com/wordpress/load-more-posts-ajax.html" rel="nofollow noreferrer">Misha Rudrastyh's "Load More" button</a>, but the code just would not load any posts. I am lost and on the verge of giving up.</p>
<p>I have a post block with a "More" link like this, ready and waiting...</p>
<p><a href="https://i.stack.imgur.com/SWOJa.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SWOJa.png" alt="enter image description here"></a></p>
<p>That corresponds to posts of "Format" taxonomy term "executive" for one taxonomy "Organisation" term. Here is the relevant portion of taxonomy-organisation.php, containing my query...</p>

</code></pre>
<p>From the tutorials and questions, I have gleaned that the process seems to be...</p>
<ul>
<li>Register/enqueue/localise a Javascript file containing the relevant code, and pass parameters to it from PHP functions.php</li>
<li>Some sort of WordPress AJAX handler in functions.php which does a WP_Query for more posts?</li>
</ul>
<p>But I am just not understanding how to implement in my situation.</p>
<p>FYI, my self-built theme is based on Bootstrap and, until now, I have de-registered WordPress' built-in <code>jquery</code>, replaced by enqueuing Bootstrap's recommended <code>https://code.jquery.com/jquery-3.3.1.slim.min.js</code> as <code>jQuery</code>. I'm not sure which is the right option, it seemed like this has a bearing on WP_Ajax_*.</p>
<p>I'm aware a similar question has been asked before, but my query seems unique and many questions/answers seem also to refer to unique situations, ie. offering answers specifically designed to work with twentyfifteen theme.</p>
<h1>Update (Feb 15, 2019):</h1>
<p>I have come a long way toward solving this, using a combination of:</p>
<ul>
<li><a href="https://artisansweb.net/load-wordpress-post-ajax/" rel="nofollow noreferrer">Artisans Web tutorial</a> for the basic concept</li>
<li><a href="https://wordpress.stackexchange.com/a/328760/39300">Anti's suggestion</a> for establishing <em>which</em> of multiple "More" links was clicked (necessary to feed unique arguments back to looped WP queries).</li>
<li>Further research/exploration based on available code, to learn how to take and pass those variables.</li>
<li>Further jQuery research to learn how to change UI elements.</li>
</ul>
<p>I can now share the following two pieces of code, which works 90% well and I could consider offering this as an answer, or Anti's answer.</p>

<p><strong>However, there is a remaining issue that I know about...</strong></p>
<p>There seems to be a Javascript issue with picking up the clicked "More" link's ID as <code>clicked_format</code> and clicking some of the <em>multiple</em> "More" links on the page. I can see this because the first few "More" clicks succeed, but then clicking a different "More" link can leave the process in the "Loading" state.</p>
<p>I suspect it is something to do with when <code>clicked_format</code> gets set and destroyed (or not). I have tried unsetting it, but to no effect.</p>
<p>Should i consider filing a separate, specific question - in either WordPress Development or StackOverflow (Javascript) - for this?</p>

] | On the taxonomy-{name}.php template for my "Organisation" taxonomy, I am currently showing a limited number of posts, grouped for each term of taxonomy "Format".
Where the number of available posts exceeds that which is displayable, I now want to enable AJAX-based loading of more posts.
I have followed countless tutorials and StackExchange questions on this topic, but something is still not clicking. For example, I implemented [Misha Rudrastyh's "Load More" button](https://rudrastyh.com/wordpress/load-more-posts-ajax.html), but the code just would not load any posts. I am lost and on the verge of giving up.
I have a post block with a "More" link like this, ready and waiting...
[](https://i.stack.imgur.com/SWOJa.png)
That corresponds to posts of "Format" taxonomy term "executive" for one taxonomy "Organisation" term. Here is the relevant portion of taxonomy-organisation.php, containing my query...
```
<?php
// This will output posts in blocks for each "Format" taxonomy term.
// But we also want to use this loop to output posts *without* a "Format" taxonomy term.
$formats = array("interview","executive","analyst","oped","","ma","earnings","financialanalysis","ipo","marketindicators","industrymoves");
foreach ($formats as $format) {
// Term of the slug above
$format_term = get_term_by('slug', $format, "format");
// Formulate the secondary tax_query for "format" with some conditionality
/* *********************************** */
/* Posts by Format */
/* *********************************** */
if (!empty($format)) {
$posts_per_page = 8;
$tax_q_format_array = array(
'taxonomy' => 'format', // from above, whatever this taxonomy is, eg. 'source'
'field' => 'slug',
'terms' => $format_term->slug,
'include_children' => false
);
// Oh, and set a title for output below
$section_title = $format_term->name;
/* *********************************** */
/* Format without Format */
/* *********************************** */
} elseif (empty($format)) {
$posts_per_page = 12;
$tax_q_format_array = array(
'taxonomy' => 'format', // from above, whatever this taxonomy is, eg. 'source'
'operator' => 'NOT EXISTS', // or 'EXISTS'
);
// Oh, and set a title for output below
$section_title = 'Reporting';
}
// Query posts
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$args = array(
// pagination
// 'nopaging' => false,
'posts_per_page' => $posts_per_page,
// 'offset' => '4',
// 'paged' => $paged,
// posts
'post_type' => array( 'article', 'viewpoint' ),
// order
'orderby' => 'date',
'order' => 'DESC',
// taxonomy
'tax_query' => array(
array(
'taxonomy' => 'company', // from above, whatever this taxonomy is, eg. 'source'
'field' => 'slug',
'terms' => $organisation->slug,
'include_children' => false
),
$tax_q_format_array
),
);
// the query
$posts_org = new WP_Query($args);
if ( $posts_org->have_posts() ) { ?>
<h5 class="mt-0 pt-2 pb-3 text-secondary"><?php echo $section_title; ?> <span class="badge badge-secondary badge-pill"><?php echo $posts_org->found_posts; ?></span></h5>
<div class="row pb-3">
<?php
while( $posts_org->have_posts() ) {
$posts_org->the_post();
get_template_part('partials/loops/col', 'vertical');
}
if ($posts_org->found_posts > $posts_per_page) {
echo '<p class="text-secondary pl-3 pb-0 load_more" style="opacity: 0.6"><i class="fas fa-plus-circle"></i> More</p>';
}
echo '</div>';
wp_reset_postdata(); // reset the query
} else {
// echo '<div class="col"><p>'.__('Sorry, no posts matched your criteria.').'</p></div>';
} // end if have_posts
}
?>
```
And here is the include file used by `get_template_part` to output post item thumbnails and links...
```
<?php
// Get fallback image if needed
@require(dirname(__FILE__).'/../source_thumbnail_fallback.php');
// @ Suppress "Notices" generated when post has no source set (ie no source at array position [0])
?>
<div class="col-sm-6 col-md-4 col-lg-3 col-xl-2 post-item overlay-bg <?php echo $display_class; ?>">
<a href="<?php the_field( 'source_url' ); ?>" class="text-dark" target="_blank">
<img src="http://www.myserver.com/to/image/location/<?php echo $source_image_url; ?>" class="img-fluid rounded mb-2">
<p><?php the_title(); ?></p>
<?php
//Do something if a specific array value exists within a post
$format_terms = wp_get_post_terms($post->ID, 'format', array("fields" => "all"));
// foreach($format_terms as $format_single) { ?>
<span class="badge <?php get_format_badge_colour_class($format_terms[0]->term_id); ?> font-weight-normal mr-2 overlay-content"><?php echo $format_terms[0]->name; ?></span>
<?php // } ?>
</a>
</div>
```
From the tutorials and questions, I have gleaned that the process seems to be...
* Register/enqueue/localise a Javascript file containing the relevant code, and pass parameters to it from PHP functions.php
* Some sort of WordPress AJAX handler in functions.php which does a WP\_Query for more posts?
But I am just not understanding how to implement in my situation.
FYI, my self-built theme is based on Bootstrap and, until now, I have de-registered WordPress' built-in `jquery`, replaced by enqueuing Bootstrap's recommended `https://code.jquery.com/jquery-3.3.1.slim.min.js` as `jQuery`. I'm not sure which is the right option, it seemed like this has a bearing on WP\_Ajax\_\*.
I'm aware a similar question has been asked before, but my query seems unique and many questions/answers seem also to refer to unique situations, ie. offering answers specifically designed to work with twentyfifteen theme.
Update (Feb 15, 2019):
======================
I have come a long way toward solving this, using a combination of:
* [Artisans Web tutorial](https://artisansweb.net/load-wordpress-post-ajax/) for the basic concept
* [Anti's suggestion](https://wordpress.stackexchange.com/a/328760/39300) for establishing *which* of multiple "More" links was clicked (necessary to feed unique arguments back to looped WP queries).
* Further research/exploration based on available code, to learn how to take and pass those variables.
* Further jQuery research to learn how to change UI elements.
I can now share the following two pieces of code, which works 90% well and I could consider offering this as an answer, or Anti's answer.

**However, there is a remaining issue that I know about...**
There seems to be a Javascript issue with picking up the clicked "More" link's ID as `clicked_format` and clicking some of the *multiple* "More" links on the page. I can see this because the first few "More" clicks succeed, but then clicking a different "More" link can leave the process in the "Loading" state.
I suspect it is something to do with when `clicked_format` gets set and destroyed (or not). I have tried unsetting it, but to no effect.
Should i consider filing a separate, specific question - in either WordPress Development or StackOverflow (Javascript) - for this?
<http://recordit.co/AI7OjJUVmH> | You can use ajax to load more posts on your archive page.
1. attach a js/jquery click event on the More link
2. send ajax request to `admin-ajax.php` (use `wp_localize_script` to get the ajax url to front end) with page number (track this with js variable).
3. handle ajax request in php. Add custom ajax actions with `add_action( 'wp_ajax_my_action', 'my_action' );` and `add_action( 'wp_ajax_nopriv_my_action', 'my_action' );` (for non-logged in users). Send `my_action` part of the action hook as ajax request `action` parameter.
4. query posts. Get the correct page (WP\_Query `paged` arg, *commented out in your code*) for the query from the ajax request, e.g. `$_POST['page']`
5. send queried posts back to front end
6. append posts from ajax response to the dom with js/jquery.
I don't think it matters that much if you use the default jQuery version or a newer one to load more posts.
Please have a look at the code examples here, <https://www.billerickson.net/infinite-scroll-in-wordpress/> (*not my blog*), for more detailed example and explanation. I know code examples are preferred to links, but the code examples written by Bill Erickson are rather long so I think it is more to convenient post a link insted of copy-pasting the examples here.
You should also have a look at the codex entry about ajax, it is really helpfull. <https://codex.wordpress.org/AJAX_in_Plugins>
I only took a cursory glance at the query function you posted, but I think it should be fine for the post most part for loading more posts with ajax.
---
**UPDATE 15.2.2019**
If you need to identify which "Load more" link/button is clicked you can do this in js/jquery.
```
// Html
<div id="posts-cat-1" class="posts-section">
// posts here
<button id="cat-name-1" class="load-more">Load more</button>
</div>
<div id="posts-cat-2" class="posts-section">
// posts here
<button class="load-more" data-category="cat-name-2">Load more</button>
</div>
<div id="cat-name-3" class="posts-section">
// posts here
<button class="load-more">Load more</button>
</div>
// jQuery
jQuery('.load-more').on('click',function(event){
// get cat name from id
var catName1 = jQuery(this).attr('id');
// or from data attribute
var catName2 = jQuery(this).attr('data-category'); // or .data('category');
// or from parent section, perhaps not ideal
var catName3 = jQuery(this).closest('.posts-section').attr('id');
// Then pass the catName to your ajax request data so you can identify which category to query in php.
});
```
---
**UPDATE 16.2.2019**
To hide the "Load more" button when there are no more posts to show you can add a simple if-else conditional to your jquery ajax call.
```
// 2. Send to query function and get results
$.post(ajaxurl, data, function(response) {
// Check if there's any content in the response.
// I think your ajax php should return empty string when there's no posts to show
if ( '' !== response ) {
// Append the returned output to this selector
$(response).appendTo('div#'+clicked_format).hide().fadeIn(2000); // was: $('div#'+clicked_format).append(response).fadeIn(4000); Reverse method, cf. https://stackoverflow.com/a/6534160/1375163
// Change link text back to original
$('a#'+clicked_format+' i').attr('class', 'fas fa-plus-circle'); // Icon
$('a#'+clicked_format+' .moretext').text('More'); // Text
// Increment "data-page" attribute of clicked link for next click
// page++;
$('a#'+clicked_format).find('span').data().page++
} else {
// This adds display:none to the button, use .remove() to remove the button completely
$('a#'+clicked_format).hide();
}
});

328,749 | <p>I use <code>get_the_content</code> to pass to a javascript variable, and then back to another PHP function. This works great, but there is an issue when using <code>get_the_content</code>. If the post contains only one line (no line breaks) it works great.
But if the post contains line breaks I get this error in the console:</p>
<p><code>SyntaxError: '' string literal contains an unescaped line break</code></p>
<p>Using <code>the_content</code> doesn't work for me in this application, as it returns nothing at all.</p>
<p>How do I solve this?</p>
<p>EDIT:</p>
<p>This is how I pass the PHP variable to Javascript on button click:</p>
<pre><code>onclick="searchEmail('<?php echo the_author_email(); ?>', '<?php echo the_title(); ?>', '<?php echo get_the_content(); ?>', '<?php echo $location ?>');"
</code></pre>
<p>And this is the javascript:</p>
<pre><code>function searchEmail(email,title,content,location) {
var $url = (admin_ajax.url);
$.ajax({
type: "POST",
url: $url,
datatype: "html",
data: { 'action': 'search_notify_email', email: email, title: title, content: content, location: location },
success: function() {
searchNotification();
},error:function() {
searchNotificationError();
}
});
}
</code></pre>
<p>And lastly, this is the PHP function which receives the variable from Javascript and sends them via email:</p>
<pre><code>function search_notify_email() {
// Set variables
$email = $_POST['email'];
$title = $_POST['title'];
$content = $_POST['content'];
$location = $_POST['location'];
// Change Email to HTML
add_filter( 'wp_mail_content_type', 'set_email_content_type' );
$to = $email;
$subject = "Test subjest";
$message = "<img src='https://example.com/favicon.png'><br><b>Test!</b>";
if (empty($title)) {
$message .= "<br><br><b>" . $_POST['content'] . "</b> test.<br> ";
}
else {
$message .= "<br><br><b>" . $_POST['content'] . "</b> test " . $_POST['title'] . " test.<br> ";
}
if (!empty($location)) {
$message .= "Test <b>" . $_POST['location'] . "</b>";
}
$headers[] = 'From: Test <[email protected]>';
if ( wp_mail($to, $subject, $message, $headers) ) {
// Success
} else {
// Error
}
die();
// Remove filter HTML content type
remove_filter( 'wp_mail_content_type', 'set_email_content_type' );
}
add_action('wp_ajax_nopriv_search_notify_email', 'search_notify_email');
add_action('wp_ajax_search_notify_email', 'search_notify_email');
// Reset Email content type to standard text/html
function set_email_content_type() {

] | I use `get_the_content` to pass to a javascript variable, and then back to another PHP function. This works great, but there is an issue when using `get_the_content`. If the post contains only one line (no line breaks) it works great.
But if the post contains line breaks I get this error in the console:
`SyntaxError: '' string literal contains an unescaped line break`
Using `the_content` doesn't work for me in this application, as it returns nothing at all.
How do I solve this?
EDIT:
This is how I pass the PHP variable to Javascript on button click:
```
onclick="searchEmail('<?php echo the_author_email(); ?>', '<?php echo the_title(); ?>', '<?php echo get_the_content(); ?>', '<?php echo $location ?>');"
```
And this is the javascript:
```
function searchEmail(email,title,content,location) {
var $url = (admin_ajax.url);
$.ajax({
type: "POST",
url: $url,
datatype: "html",
data: { 'action': 'search_notify_email', email: email, title: title, content: content, location: location },
success: function() {
searchNotification();
},error:function() {
searchNotificationError();
}
});
}
```
And lastly, this is the PHP function which receives the variable from Javascript and sends them via email:
```
function search_notify_email() {
// Set variables
$email = $_POST['email'];
$title = $_POST['title'];
$content = $_POST['content'];
$location = $_POST['location'];
// Change Email to HTML
add_filter( 'wp_mail_content_type', 'set_email_content_type' );
$to = $email;
$subject = "Test subjest";
$message = "<img src='https://example.com/favicon.png'><br><b>Test!</b>";
if (empty($title)) {
$message .= "<br><br><b>" . $_POST['content'] . "</b> test.<br> ";
}
else {
$message .= "<br><br><b>" . $_POST['content'] . "</b> test " . $_POST['title'] . " test.<br> ";
}
if (!empty($location)) {
$message .= "Test <b>" . $_POST['location'] . "</b>";
}
$headers[] = 'From: Test <[email protected]>';
if ( wp_mail($to, $subject, $message, $headers) ) {
// Success
} else {
// Error
}
die();
// Remove filter HTML content type
remove_filter( 'wp_mail_content_type', 'set_email_content_type' );
}
add_action('wp_ajax_nopriv_search_notify_email', 'search_notify_email');
add_action('wp_ajax_search_notify_email', 'search_notify_email');
// Reset Email content type to standard text/html
function set_email_content_type() {
return 'text/html';
}
``` | It sounds like you are directly echoing the php into a JavaScript variable? get\_the\_content makes no guarantees that the value it returns will be sanitized in the right way for a JavaScript variable.
You might try first encoding the output into JSON, and then doing that, i.e.
```
<script>
<?php
ob_start();
the_content();
$content = ob_get_clean();
?>
var myVariable = <?php echo json_encode( $content ); ?>;
</script>
```
To be honest it may not even work. It's hacky. Dropping php into JavaScript like this is really not a recommended practice, for exactly the reason you're encountering. What this solution does is poorly imitate the proper approach for when you have PHP data (i.e. the\_content) that you need in JavaScript -- AJAX.
Your JavaScript code should ask your PHP code to nicely provide sanitized data, i.e. it should make an AJAX request back to the server and your PHP code will have the opportunity to run, sanitize, and return the data cleanly. |

<p>I also noticed it adds a class in the same place for every category i put these post items into.</p>

] | I noticed in my wordpress/woocommerce setup that every time i add a tag to a product or a blog post. It adds that tag as a class into the listed item (Product/blog)
I also noticed it adds a class in the same place for every category i put these post items into.
How can i prevent wordpress and woocommerce from addings these tag and category names into my html markup as classes? As i do not need them and its creating a mess.
Thanks for any help! I could not locate a similar function anywhere. | You can (at the moment) not use InnerBlocks more than once within a block. However, you can bypass this by using a template for your InnerBlocks that contain Blocks which support InnerBlocks instead, like the core/column block.
Like this:
```
wp.element.createElement(InnerBlocks, {
template: [['core/column',{},[['core/paragraph',{'placeholder':'Inhalt linke Spalte'}]]],['core/column',{},[['core/paragraph',{'placeholder':'Inhalt rechte Spalte'}]]]],
templateLock: "all",
allowedBlocks: ['core/column']});
```
Some time ago, i wrote a Block for a content/sidebar block with align left/right attributes, worked exactly like that.
Happy Coding! |

] | Hi everyone I have a question how can you create a dynamic copyright in WordPress with URL that goes back to the home page as well as a URL that goes to the designer of the theme | The fastest way is to look for the current copyright text inside your theme's `footer.php` file and substitute it with something more of your liking.
My suggestion, as I don't know what you mean for "dynamic", is to substitute the current text with a function call, like `<?php my_copyright_text() ?>`, and then define that function in your theme's `function.php` file in which you do whatever you need to do.
```php
function my_copyright_text(){
$year = date("Y",time());
$company = "Mycompany.com";
echo "© 2018-$year $company"; //this is effectively HTML code
}
```
As the output of the function is HTML code you can insert tags and css classes as you like. For example `"© 2018-$year <span class="company">Mycompany.com</span>"`.
**It is strongly suggested to [use a child theme](https://developer.wordpress.org/themes/advanced-topics/child-themes/)**, as not to let theme updates overwrite your tweaks.
If you feel brave you can put some of the parameters in the theme customizer, [take a look here](https://developer.wordpress.org/themes/customize-api/). |

<a class="some-class" href="#">menu2</a>
<a class="some-class" href="#">menu3</a>
<a class="some-class is-active" href="/sell">Menu4</a>
</div>`
I have tried with this method:
`$menuLocations = get_nav_menu_locations();
$menuID = $menuLocations['primary'];
$primaryNav = wp_get_nav_menu_items($menuID);
foreach ( $primaryNav as $navItem ) {
echo '<a class="some-class" href="'.$navItem->url.'" title="'.$navItem->title.'">'.$navItem->title.'</a>';
}`
I am getting good output. only problem with active menu item.
I am trying to add class `is-active` for the active navigation menu.
Thanks.
(updated question) | You don't need to write a custom walker to achieve this. You can modify the output of the `wp_nav_menu()` function and hook into the appropriate default nav menu filter to modify the output of the individual menu items. E.g. (assuming your theme menu location is called primary)
Put this in your functions.php file
```
/**
* Output Custom Menu
*
* Call this function within your template
* files wherever you want to output your
* custom menu.
*
*/
function custom_theme_menu() {
$menu = wp_nav_menu( array(
'theme_location' => 'primary',
'container_class' => 'menu',
'items_wrap' => '%3$s', // needed to remove the <ul> container tags
'fallback_cb' => false,
'echo' => false
) );
// Strip out the <li> tags from the output.
echo strip_tags( $menu,'<a>, <div>' );
}
/**
* Add Nav Menu Item Link Classes
*
* Detects if we are rendering the custom menu
* and adds the appropriate classnames.
*
*/
function custom_theme_nav_menu_link_attributes( $atts, $item, $args, $depth ) {
// For all other menus return the defaults.
if ( $args->theme_location !== 'primary' ) {
return $atts;
}
// Add the link classes.
$class_names = array( 'some-class' );
if ( $item->current ) {
$class_names[] = 'is-active';
}
$atts['class'] = join( ' ', $class_names );
return $atts;
}
add_filter( 'nav_menu_link_attributes', 'custom_theme_nav_menu_link_attributes', 10, 4 );
```
Then in your template files just call the following function wherever you want to output the menu:
```
custom_theme_menu();

```
add_filter( 'upload_mimes', function ( $mime_types ) {
$mime_types[ 'eps' ] = 'application/postscript';

} );

After that I can upload several different EPS files locally on my development machine (Windows 10, PHP 7.0.19). However, on the remote server (CentOS, PHP 7.2.15), I still get the error message for *certain* EPS files.
After some debugging and troubleshooting I realized that the PHP versions differed so I downgraded PHP to version 7.0.33 on the remote server and suddenly I could upload all EPS files.
Any ideas regarding what the problem might be? Has something changed between PHP 7.0 and 7.2 that would make the `upload_mimes` filter fail?
WordPress is the latest version, 5.0.3. | In recent versions of WordPress ([5.0.1](https://make.wordpress.org/core/2018/12/13/backwards-compatibility-breaks-in-5-0-1/) or higher) file upload security has been tightened by actually checking the content of an uploaded file using the PHP function [finfo\_file()](http://php.net/manual/en/function.finfo-file.php) to determine if the file extension matches the MIME type. This has proven problematic since files with the same file type and extension may yield different MIME types.
In my case one EPS file (let's call it `one.eps`) was detected as "application/postscript" while another file (let's call it `two.eps`) as "image/x-eps" or "application/octet-stream" depending on which PHP version the server was running.
After adding the below PHP snippet I was consistently able to upload file `one.eps` to the WordPress Media Library no matter what version of PHP I was using. But the file `two.eps` could not be uploaded if the server was running PHP 7.2 or higher.
```
add_filter( 'upload_mimes', function ( $mime_types ) {
$mime_types[ 'eps' ] = 'application/postscript';
return $mime_types;
} );
```
I'm by no means an expert on the EPS file format but I think it's safe to assume that different variations on the format exists. Opening the two files in different applications and checking the content strengthens this belief:
Opening the files in a text editor:
* `one.eps` Has an ASCII/human readable file header
* `two.eps` Appears binary
Format according to GIMP:
* `one.eps` application/postscript
* `two.eps` image/epsf
Format according to finfo\_file() on PHP 7.0.10:
* `one.eps` application/postscript
* `two.eps` application/octet-stream
Format according to finfo\_file() on PHP 7.3.2:
* `one.eps` application/postscript
* `two.eps` image/x-eps
In the WordPress core file `wp-includes/functions.php`, function `wp_check_filetype_and_ext()` you will find the following:
```
// fileinfo often misidentifies obscure files as one of these types
$nonspecific_types = array(
'application/octet-stream',
'application/encrypted',
'application/CDFV2-encrypted',
'application/zip',
);
```
Further down in the function there is a hard-coded exception to allow these MIME types under certain circumstances. This is what made it possible to upload `two.eps` on earlier PHP versions, since `finfo_file()` reported "application/octet-stream" as its MIME type and this is one of the hard-coded exceptions.
Unfortunately, there seems to be no mechanism in WordPress to allow the same extension to be mapped to different MIME types, which (to me) would be the most obvious solution. Something along the lines of:
```
add_filter( 'upload_mimes', function ( $mime_types ) {
$mime_types[ 'eps' ] = array('application/postscript', 'image/x-eps');
return $mime_types;
} );
```
However, the user @birgire [posted a workaround as an answer](https://wordpress.stackexchange.com/questions/323750/how-to-assign-multiple-file-mime-types-to-extension/323757#323757) to a similar question. |
328,852 | <p>I have this piece of code and, although it works, I do not understand how.
First, I created a custom post type into my mu-plugins folder:</p>
<pre><code>function actor_init() {
$args = array(
'label' => 'actors',
'description' => 'hollywood & stuff',
'supports' => array(
'thumbnail',
'title',
'editor',
'comments'
),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
);
register_post_type('actor', $args);
}
</code></pre>
<p>then, in functions.php I hooked it.</p>
<pre><code>add_action( 'init', 'actor_init' );
</code></pre>
<p>Also, inside functions.php I created a function to display, if there is, the title of the post / page / custom-post</p>
<pre><code><?php
function provahel($arg) {
if (!$arg['title']) {
$arg['title'] = get_the_title();
}
?>
<h1><?php echo $arg['title'] ?></h1>
<?php } ?>
</code></pre>
<p>Finally, In my page.php, single-actor.php and single.php files I call the function inside the loop.</p>
<pre><code><?php
while(have_posts()) {
the_post();
provahel($argf);
?>
</code></pre>
<p>On the front end, correctly the title of the post gets rendered, either if it is a page, a post or the custom-post-type (in this case actor). Why? How Wordpress knows what parameter is passed into the provahel() functions? What is this parameter $argf (P.S. could be called in any way and it would still work)?<br>
Thanks in advance for any contribution. </p>

Thanks in advance for any contribution. | In recent versions of WordPress ([5.0.1](https://make.wordpress.org/core/2018/12/13/backwards-compatibility-breaks-in-5-0-1/) or higher) file upload security has been tightened by actually checking the content of an uploaded file using the PHP function [finfo\_file()](http://php.net/manual/en/function.finfo-file.php) to determine if the file extension matches the MIME type. This has proven problematic since files with the same file type and extension may yield different MIME types.
In my case one EPS file (let's call it `one.eps`) was detected as "application/postscript" while another file (let's call it `two.eps`) as "image/x-eps" or "application/octet-stream" depending on which PHP version the server was running.
After adding the below PHP snippet I was consistently able to upload file `one.eps` to the WordPress Media Library no matter what version of PHP I was using. But the file `two.eps` could not be uploaded if the server was running PHP 7.2 or higher.
```
add_filter( 'upload_mimes', function ( $mime_types ) {
$mime_types[ 'eps' ] = 'application/postscript';
return $mime_types;
} );
```
I'm by no means an expert on the EPS file format but I think it's safe to assume that different variations on the format exists. Opening the two files in different applications and checking the content strengthens this belief:
Opening the files in a text editor:
* `one.eps` Has an ASCII/human readable file header

328,862 | <p>I try to implement a function to notify users about changes on the webpage. I tried to use sessions for that but it did not work very well. For example:</p>
<p>A User can attend an event. To do that he has to register for it. So the status of his registration is 'on hold' at that moment. In the backend, i can accept his registration and change the status to 'accepted'. Now I want the user to see a notification on his dashboard that he was accepted.</p>
<p>For this, I use his last login date. I check if the change_date of his status was after his last login date. The value for registration_notifications is stored in a wp_session variable. This works without problem. If the user opens the page with the list of his registrations, this wp_session variable is reseted. And here comes the problem:</p>
<p>If I now change the status of a second registration of the same user, the notification is not shown.</p>
<p>My codes:</p>
<p>the function to get the notifications:</p>
<pre><code>if(!isset(wp_session['event'])){

<p>change session on the overview page:</p>

328,934 | <p>I moved my WordPress installations from my old server to a new one.
I copied all databases..etc and things seem to be working fine. (I have already migrated servers before, so I guess I know how to do the migration part correctly).
However I only have one problem with ALL my wp installations, when adding new items to navigation menu, the “add to menu” doesn’t work.
This video illustrates my problem: <a href="https://drive.google.com/file/d/1hEa2lNkavCm-EFfU7Ct8c88LOhRH9vl1/view" rel="nofollow noreferrer">https://drive.google.com/file/d/1hEa2lNkavCm-EFfU7Ct8c88LOhRH9vl1/view</a></p>
<p>I even did a new test installation from scratch just to see if the problem is due to copying files from another server, but I still have this issue with the new installation. So I guess it might be a server issue?</p>
<p>When I click add to menu the page reloads(which is unusual) then this appears in my console:</p>
<blockquote>
<p>"[Violation] Added non-passive event listener to a scroll-blocking
‘touchstart’ event. Consider marking event handler as ‘passive’ to
make the page more responsive. See

I tried changing these in my php.ini</p>
<pre><code>post_max_size 20M
max_input_vars 10000
</code></pre>
<p>But it didn't solve the issue, however now nothing appears in the console.</p>

<pre><code>define('WP_DEBUG', true);

] | I moved my WordPress installations from my old server to a new one.
I copied all databases..etc and things seem to be working fine. (I have already migrated servers before, so I guess I know how to do the migration part correctly).
However I only have one problem with ALL my wp installations, when adding new items to navigation menu, the “add to menu” doesn’t work.
This video illustrates my problem: <https://drive.google.com/file/d/1hEa2lNkavCm-EFfU7Ct8c88LOhRH9vl1/view>
I even did a new test installation from scratch just to see if the problem is due to copying files from another server, but I still have this issue with the new installation. So I guess it might be a server issue?
When I click add to menu the page reloads(which is unusual) then this appears in my console:
>
> "[Violation] Added non-passive event listener to a scroll-blocking
> ‘touchstart’ event. Consider marking event handler as ‘passive’ to
> make the page more responsive. See
> chromestatus.com/feature/5745543795965952
>

>
" in load-scripts.php
I tried changing these in my php.ini
```
post_max_size 20M
max_input_vars 10000
```
But it didn't solve the issue, however now nothing appears in the console.
I tried clearing my browser cache and the .htaccess file and I already have the following in my wp-config right before "that's all stop editing"
```
define('WP_DEBUG', true);
define( 'CONCATENATE_SCRIPTS', true );
define( 'WP_MEMORY_LIMIT', '256M' );
```
The old server uses mariaDB 5.5, the new one uses 10.2, I’m not sure if this is related to the problem though…

And thanks in advance | PHP only runs when you request a page. When the request is over, everything is gone. It's not like a Node application where the same program handles all the requests and variables can persist across pages just by defining them, so doing things with a `$wp_session` variable will only do things on that request.
If you navigate to another page, it has to load WordPress again from scratch, and figure everything out fresh. This is why your code doesn't work, and that's how all PHP programs work.
If you want to persist something, you have to store it somewhere, such as the database, the filesystem, or an object cache. That's what things like user meta for logged in users are used for.
There is 1 exception, PHP Sessions using `$_SESSION` variables, but, they're not used by WordPress and need some setup. Additionally, they're incompatible with page caching solutions such as Varnish, Supercache, etc. Additionally, not all hosts support it. For example, PHP Sessions will not work correctly on WP Engine.
Other notes:
* In PHP variables begin with `$` but yours don't for some reason. I would have expected PHP fatal errors.
* Global variables need to be declared before they're used
* You're doing an SQL query then dumping the result in a variable with no error processing which is a security risk
* You're displaying the result of that query without any formatting or escaping, which is also a security risk
* You need to end each statement in a `;`, your show notification example doesn't do this, and will generate syntax errors
* `wp_session` is never created anywhere, so initially it's completely undefined. This will generate warnings and notices at runtime that fill your PHP error log |

But...
------
if there are a lot of occurrences of `get_avatar` or you don't want to modify these occurrences (for example some of them come from plugins), then you can achieve this using filters.
One way to do this would be to use [`pre_get_avatar`](https://developer.wordpress.org/reference/hooks/pre_get_avatar/) filter.
If you'll return any non-null value, the rest of `get_avatar` function will get ignored and your result will be used as avatar. So you can use something like this, to do the trick:
```
function replace_all_avatars_with_default_one( $html, $id_or_email, $args ) {
$url = '<URL TO DEFAULT AVATAR';
$class = array();
return $avatar = sprintf(
"<img alt='%s' src='%s' class='%s' height='%d' width='%d' %s/>",
esc_attr( $args['alt'] ),
esc_url( $url ),
esc_attr( join( ' ', $class ) ),
(int) $args['height'],
(int) $args['width'],
$args['extra_attr']
);
}
add_filter( 'pre_get_avatar', 'replace_all_avatars_with_default_one', 10, 3 );

But I'm trying to display only those sub-taxonomies of <strong>selected</strong> parent taxonomy (not all the sub-taxonomies from other parent taxonomies). For example, if I select a parent taxonomy from the first dropdown, then second dropdown should only display the sub-taxonomies of it. I'm not finding any <code>php</code> logic to achieve this goal. I'm displaying these two dropdowns on 'Edit Profile' page. Here is my code on <code>functions.php</code></p>

Updated Feb 19, 2019: script.js added and few lines on functions.php to receiving JS variable. | Here's a fully functional snippet for doing this.
* I added the correct WordPress table stylings
* This requires adding my `smyles_get_taxonomy_hierarchy` to add children of taxonomy to the term object
* This hides the child dropdown if no children exist
* This handles everything (and saves) based on `TERM ID` not the `NAME` .. you should always use term ID as if you decide to change the wording/slug later on you will have all kinds of issues

Seems code syntax highlighter on here can't handle mix of HTML/JS/PHP, so here's a GitHub Gist of working code:
<https://gist.github.com/tripflex/527dd82db1d1f3bf82f761486fcc3303>
Breakdown:
You first need to include my function to generate taxonomy array with children in that term object:
```
if ( ! function_exists( 'smyles_get_taxonomy_hierarchy' ) ) {
/**
* Recursively get taxonomy and its children
*
* @param string $taxonomy
* @param int $parent Parent term ID (0 for top level)
* @param array $args Array of arguments to pass to get_terms (to override default)
*
* @return array
*/
function smyles_get_taxonomy_hierarchy( $taxonomy, $parent = 0, $args = array( 'hide_empty' => false ) ) {
$defaults = array(
'parent' => $parent,
'hide_empty' => false
);
$r = wp_parse_args( $args, $defaults );
// get all direct decendants of the $parent
$terms = get_terms( $taxonomy, $r );
// prepare a new array. these are the children of $parent
// we'll ultimately copy all the $terms into this new array, but only after they
// find their own children
$children = array();
// go through all the direct decendants of $parent, and gather their children
foreach ( $terms as $term ) {
// recurse to get the direct decendants of "this" term
$term->children = smyles_get_taxonomy_hierarchy( $taxonomy, $term->term_id );
// add the term to our new array
$children[ $term->term_id ] = $term;
}
// send the results back to the caller
return $children;
}
}
```
jQuery/JavaScript code handling:
```
jQuery( function($){
// slcustom_categories var should be available here
$('#parent_category').change( function(e){
var child_cat_select = $( '#child_category' );
var term_id = $(this).val();
console.log( 'Parent Category Changed', term_id );
// Remove any existing
child_cat_select.find( 'option' ).remove();
// Loop through children and add to children dropdown
if( slcustom_categories && slcustom_categories[ term_id ] && slcustom_categories[ term_id ]['children'] ){
console.log( 'Adding Children', slcustom_categories[ term_id ]['children'] );
$.each( slcustom_categories[term_id]['children'], function( i, v ){
console.log( 'Adding Child: ', v );
child_cat_select.append( '<option value="' + v['term_id'] + '">' + v[ 'name' ] + '</option>');
});
// Show if child cats
$( '#child_category_row' ).show();
} else {
// Hide if no child cats
$( '#child_category_row' ).hide();
}
});
// Trigger change on initial page load to load child categories
$('#parent_category').change();
});
```
Function to output fields:
```
function slcustom_user_profile_fields( $user ){
$categories = smyles_get_taxonomy_hierarchy( 'project_category' );
$parent_category = $user->parent_category;
$child_category = $user->child_category;
// $parent_category = 52; // used for testing
// $child_category = 82; // used for testing
$parent_has_children = ! empty( $parent_category ) && $categories[ $parent_category ] && ! empty( $categories[ $parent_category ]->children );
// Creative way to use wp_localize_script which creates a JS variable from array
// You should actually change this to load your JavaScript file and move JS below to that file
wp_register_script( 'slcustom_user_profile_fields', '' );
wp_localize_script( 'slcustom_user_profile_fields', 'slcustom_categories', $categories );
wp_enqueue_script( 'slcustom_user_profile_fields' );
?>

329,007 | <p>I am trying to build an Custom Post Type for showing information about events. The Custom Post Type has name 'Event', with the following meta fields: </p>
<ul>
<li>event_startdate <em>(date in format YYYY-MM-DD)</em></li>
<li>event_enddate <em>(date in format YYYY-MM-DD)</em></li>
</ul>
<p>This works fine for the single-event listing, however in the archive listing I would like to see a grouping like: </p>
<h2>2019</h2>
<h3>March</h3>
<ul>
<li>Title of event starting in march</li>
<li>Title of another event starting in march</li>
</ul>
<h3>May</h3>
<ul>
<li>Title of may event</li>
</ul>
<h3>December</h3>
<ul>
<li>Title of Christmas event</li>
</ul>
<h2>2020</h2>
<h3>January</h3>
<ul>
<li>Title of 2020 vision event</li>
</ul>
<p>I have found some questions and answers on using wp_get_archives(), however this seems to group the posts by published date, rather on the actual date of the event (event.startdate). I also found some posts on sorting by metavalue, however not grouping. Thanks in advance for any advice or hint on how to accomplish this!</p>

] | I am trying to build an Custom Post Type for showing information about events. The Custom Post Type has name 'Event', with the following meta fields:
* event\_startdate *(date in format YYYY-MM-DD)*
* event\_enddate *(date in format YYYY-MM-DD)*
This works fine for the single-event listing, however in the archive listing I would like to see a grouping like:
2019
----
### March
* Title of event starting in march
* Title of another event starting in march
### May
* Title of may event
### December
* Title of Christmas event
2020
----
### January
* Title of 2020 vision event
I have found some questions and answers on using wp\_get\_archives(), however this seems to group the posts by published date, rather on the actual date of the event (event.startdate). I also found some posts on sorting by metavalue, however not grouping. Thanks in advance for any advice or hint on how to accomplish this! | OK, so this problem has two parts:
1. Make WordPress to sort these posts properly.
2. Make WordPress to display them with all that grouping.
1. Sorting CPT by meta value on archive
---------------------------------------
You can use `pre_get_posts` to achieve this.
```
add_action( 'pre_get_posts', function ( $query ) {
if ( is_post_type_archive( 'event' ) && $query->is_main_query() ) {
$query->set( 'orderby', 'meta_value' );
$query->set( 'order', 'ASC' );
$query->set( 'meta_key', 'event_startdate' );
}
} );
```
So now events will be sorted ascending by start\_date.
2. Displaying and grouping
--------------------------
You'll have to modify the `archive-event.php` file, so these events get in their groups.
```
<?php
$current_year = $current_month = '';
while ( have_posts() ) :
the_post();
$last_year = $current_year;
$last_month = $current_month;
$current_year = date( 'Y', strtotime( get_post_meta( get_the_ID(), 'event_startdate', true ) ) );
if ( $last_year != $current_year ) {
$last_month = '';
}
$current_month = date( 'F', strtotime( get_post_meta( get_the_ID(), 'event_startdate', true ) ) );
?>
<?php if ( $last_year != $current_year ) : ?><h2><?php echo $current_year; ?></h2><?php endif; ?>
<?php if ( $last_month != $current_month ) : ?><h3><?php echo $current_month; ?></h3><?php endif; ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php endwhile; ?>

] | Display featured image file size, extension, filename, type, orientation?
How to display some information of featured image in post.
I need to display like this in post:
Detail Of Easter Desktop Wallpaper Widescreen
Posted : February 13, 2017 At 9:46 Am
Author : Admin
Category : Easter
Tags : Beautiful, Cool, Desktop
Viewed : 1334 Visitor

pls, i am newbie, make it easy for me to understand. thnks | The featured image is just an attachment, and you can retrieve its post ID via `get_post_thumbnail_id`, e.g.
```
$featured_image_id = get_post_thumbnail_id( $post );
```
At which point you're dealing with a standard post of type `attachment`. Other than checking that there is a featured image, no special handling is needed and it can be treated as any other attachment post.
In fact, internally setting the featured image is just putting a post ID in a particular post meta field.
```
function get_post_thumbnail_id( $post = null ) {
$post = get_post( $post );
if ( ! $post ) {
return '';
}
return get_post_meta( $post->ID, '_thumbnail_id', true );
}
```
Though I would recommend using the function instead of going straight for the post meta.
As for how to get the size, type, format of an `attachment` post, that's another question that you should open a new question for ( or refer to the main good answers that already exist ) |

If you have this in your plugin:
```
function sp_echo_site() {
echo get_site_url();
}
```
Then you call this function as this:
```
sp_echo_site();
```
And this line will run this function in the context of current site.
So you'll have to do something like this:
```
if ( function_exists( 'get_sites' ) ) {
foreach ( get_sites() as $site ) {
switch_to_blog( $site->blog_id );
sp_echo_site();
restore_current_blog();
}
}

329,089 | <p>Quick heads up, I know nothing much about php so I might need some extra help with this.
So, I have set up a while ago a child theme for Astra in Wordpress. And while everything is working well so far, I just noticed that the customizer preview page is not working, or rather not fully loading at all.</p>
<p>I went through the whole plugins deactivation stuff, but it didn't change anything, so when I switched to my parent theme, I noticed the customizer works. Meaning that the problem is from my child theme.</p>
<p>I'll put below what I have in both the style.css and functions.php files of my child theme, please do let me know if something is wrong.</p>
<pre><code>/*
Theme Name: X Child Theme // Made by Y
Author: Y
Description:
Template: astra
*/
</code></pre>
<p>Functions.php files</p>
<pre><code><?php
function astra_child_enqueue_parent_theme_style() {
// Dynamically get version number of the parent stylesheet (lets browsers re-cache your stylesheet when you update your theme)
$theme = wp_get_theme( 'astra' );
$version = $theme->get( 'Version' );
// Load the stylesheet
wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css', array(), $version );
}
add_action( 'wp_enqueue_scripts', 'astra_child_enqueue_parent_theme_style' );
?>
</code></pre>
<p>Thoughts?</p>
<p>Edit: My bad, I actually meant to write template there. It is declared as Templare: in the style.css file. and the comment blocks are there as well. I will edit it my post to fix it. Thanks a lot anyway</p>

If you have this in your plugin:
```
function sp_echo_site() {
echo get_site_url();
}
```
Then you call this function as this:
```
sp_echo_site();
```
And this line will run this function in the context of current site.
So you'll have to do something like this:
```
if ( function_exists( 'get_sites' ) ) {
foreach ( get_sites() as $site ) {
switch_to_blog( $site->blog_id );
sp_echo_site();
restore_current_blog();
}
}

So it should be:

] | I am designing a website using the [Renden Free theme](https://www.thinkupthemes.com/free/renden-free/), and my problem is that some long titles, when viewed in mobile, have words broken in half. For example:
[](https://i.stack.imgur.com/k3sT9.jpg)
As you can see, the word "Corporal" gets broken and split in two lines.
Why is this? Is there any way to control where does Wordpress split the title? | It's possible that a word-break CSS rule could fix the problem. You could apply it globally with this
```
body {word-break:normal !important; }
```
Or maybe this:
```
body {overflow-wrap: normal;}
```
But it might be better to apply that to the specific class/id used by the title. And ever further tweak it to only apply that rule to smaller screens via the media query.
But you could add the above to 'additional CSS' in your theme customization to see if that will help.
Asking the theme developer support area is the best place for this question, though. |

Everything works fine, data gets inserted into my database table.
Now, this is how I display the messages:
```
<div id="messages">

}
```
My question is, **where/when** do I call `load_projectmessages`? Should I modify my whole JS ajax code to also do the displaying of new data? | Modify your code as follows:
```
add_action('wp_ajax_send_projectmessage', 'send_projectmessage');
function send_projectmessage() {
global $wpdb;
$wpdb->insert( //insert stuff to db table));
// Call your function to retrieve your data and send it to browser
$messages = load_projectmessages($projectid);
wp_send_json_success($messages);
}
```
Display data through JS by modifying this
```
ajaxRequest.done(function(data) { console.log(data); });
```
to this
```
ajaxRequest.done(function(data) {
// Put markup for retrieved data here
// for example
var o = "<table><tr><td>Project ID</td><td>Message</td></tr>";
for (i=0; i<=data.length; i++){
o .= "<tr><td>"+data.projectid+"</td><td>"+data.message"+</td></tr>";
}
o .= "</table>";
$(#messages).html(o);
});
```
Also make sure that your function return an array instead of an OBJECT, so modify it as follows:
```
function load_projectmessages($projectid) {
global $wpdb;
$sql_displaymessages = $wpdb->prepare("sql stuff", $projectid );
// Add ARRAY_A to get result in an associative array
$projectmessages = $wpdb->get_results($sql_displaymessages, ARRAY_A);
return $projectmessages;
// Not needed
// wp_die();

So that is the correct data being pulled from the database but as you can see it is not being displayed in the table as coded. What is my next step to try and get this to render in a nicely constructed table?
Furthermore...if someone knows, can you explain how I can put a place on this page to to select a date and then the data pulled from the database be from that date?
I am trying to do everything in shortcode. | It's not displayed as table, because you don't return correct HTML code. Let's take a look at your code (I've put comments at end of incorrect lines):
```
$content = '<table>';
$content .= '</tr><th>Week Beginning</th><th>Monday</th><th>Tuesday</th><th>Wednesday</th><th>Thursday</th><th>Friday</th><th>Saturday</th><th>Sunday</th><th>Weekly Total</th><th>Previous Week Totals</th></tr>'; // <- here you open TR with </tr>, so it's already incorrect
$results = $seconddb->get_results( ' SELECT * FROM seconddb_PontoonBoats_LineOne_2Log' );
foreach ( $results AS $row ) {
$content = '<tr>'; // <- here you overwrite previous value of $content with string '<tr>'
// Modify these to match the database structure
$content .= '<td>' . $row->{'Week Beginning'} . '</td>';
$content .= '<td>' . $row->Monday . '</td>';
$content .= '<td>' . $row->Tuesday . '</td>';
$content .= '<td>' . $row->Wednesday . '</td>';
$content .= '<td>' . $row->Thursday . '</td>';
$content .= '<td>' . $row->Friday . '</td>';
$content .= '<td>' . $row->Saturday . '</td>';
$content .= '<td>' . $row->Sunday . '</td>';
$content .= '<td>' . $row->{'Weekly Total'} . '</td>';
$content .= '<td>' . $row->{'Previous Week Totals'} . '</td>';
$content .= '</tr>';
}
$content .= '</table>';
```
So your function returns something like this, if there are no rows (it's incorrect HTML):
```
<table>
</tr><th>Week Beginning</th><th>Monday</th><th>Tuesday</th><th>Wednesday</th><th>Thursday</th><th>Friday</th><th>Saturday</th><th>Sunday</th><th>Weekly Total</th><th>Previous Week Totals</th></tr>
</table>
```
And something like this, if there are any rows found:
```
<tr>
<td><VALUE FOR: $row->{'Week Beginning'}></td>
<td><VALUE FOR: $row->Monday></td>
<td><VALUE FOR: $row->Tuesday></td>
<td><VALUE FOR: $row->Wednesday></td>
<td><VALUE FOR: $row->Thursday></td>
<td><VALUE FOR: $row->Friday></td>
<td><VALUE FOR: $row->Saturday></td>
<td><VALUE FOR: $row->Sunday></td>
<td><VALUE FOR: $row->{'Weekly Total'}></td>
<td><VALUE FOR: $row->{'Previous Week Totals'}></td>
</tr>
</table>
```
And here's the fixed version of that function:
```
function pontoon_table_shortcode( $args ) {
global $seconddb;
// Shortcodes RETURN content, so store in a variable to return
$content = '<table>';
$content .= '<tr><th>Week Beginning</th><th>Monday</th><th>Tuesday</th><th>Wednesday</th><th>Thursday</th><th>Friday</th><th>Saturday</th><th>Sunday</th><th>Weekly Total</th><th>Previous Week Totals</th></tr>';
$results = $seconddb->get_results( ' SELECT * FROM seconddb_PontoonBoats_LineOne_2Log' );
foreach ( $results AS $row ) {
$content .= '<tr>';
// Modify these to match the database structure
$content .= '<td>' . $row->{'Week Beginning'} . '</td>';
$content .= '<td>' . $row->Monday . '</td>';
$content .= '<td>' . $row->Tuesday . '</td>';
$content .= '<td>' . $row->Wednesday . '</td>';
$content .= '<td>' . $row->Thursday . '</td>';
$content .= '<td>' . $row->Friday . '</td>';
$content .= '<td>' . $row->Saturday . '</td>';
$content .= '<td>' . $row->Sunday . '</td>';
$content .= '<td>' . $row->{'Weekly Total'} . '</td>';
$content .= '<td>' . $row->{'Previous Week Totals'} . '</td>';
$content .= '</tr>';
}
$content .= '</table>';
// return the table
return $content;

329,683 | <p>We use automatic updates on our sites due to having many sites and so manual updates not being feasible in the low hosting costs.</p>
<p>But due to Wordpress or mainly plugin updates having the possibility to break your site, and due to not knowing when Wordpress would actually do the updates which could also occur every day, I would like to programatically update Wordpress and plugins in a functions.php or plugin so I can know the exact date and time it will run, and so we know to check for problems afterwards.</p>
<p>For example, I may choose Monday mornings 3am so our first action that morning is check all sites are working well, fix any issues, and then I know the rest of the week will be problem free :) </p>
<p><strong>Does anyone know how to initiate a Wordpress and plugin update in the functions file or a plugin?</strong> </p>
<p>My idea is to disable all automatic updates generally, but then at a certain day and time to call the update function which would check if updates exist, and if they do, update them. I will add an email function to inform me what has been updated on what site so I can check that site. </p>
<p>If using automatic updates, this approach is far more controlled than if leaving Wordpress do it as and when it likes however many times every day. </p>
<p>Thanks</p>

] | We use automatic updates on our sites due to having many sites and so manual updates not being feasible in the low hosting costs.
But due to Wordpress or mainly plugin updates having the possibility to break your site, and due to not knowing when Wordpress would actually do the updates which could also occur every day, I would like to programatically update Wordpress and plugins in a functions.php or plugin so I can know the exact date and time it will run, and so we know to check for problems afterwards.
For example, I may choose Monday mornings 3am so our first action that morning is check all sites are working well, fix any issues, and then I know the rest of the week will be problem free :)
**Does anyone know how to initiate a Wordpress and plugin update in the functions file or a plugin?**
My idea is to disable all automatic updates generally, but then at a certain day and time to call the update function which would check if updates exist, and if they do, update them. I will add an email function to inform me what has been updated on what site so I can check that site.
If using automatic updates, this approach is far more controlled than if leaving Wordpress do it as and when it likes however many times every day.
Thanks | There's a question and an answer regarding WP (auto) updates here, [How To/What triggers a Wordpress auto update?](https://wordpress.stackexchange.com/questions/183202/how-to-what-triggers-a-wordpress-auto-update)
The answer also has a link to a blog post on how to [force WordPress auto-update](http://blog.birdhouse.org/2013/11/02/force-wordpress-auto-update/).
Code snippet posted on the referenced blog,
```
<?php
// request-update.php
require( dirname(__FILE__) . '/wp-load.php' );
wp_maybe_auto_update();
?>
```
and
```
php ./request-update.php
```
Perhaps you can use this and a real (not WP) cron job to update your site(s) at a certain day and time.
**Edit**
Then there's the [`do_core_upgrade`](https://developer.wordpress.org/reference/functions/do_core_upgrade/) function.
**Edit 2**
Oh, and then there's [`wp_update_plugins`](https://developer.wordpress.org/reference/functions/wp_update_plugins/) and [`wp_update_themes`](https://developer.wordpress.org/reference/functions/wp_update_themes/), too. These are defined in [wp-includes/update.php](https://core.trac.wordpress.org/browser/tags/5.1/src/wp-includes/update.php) (trac).
**Edit 3**
Actually, [`wp_ajax_update_plugin`](https://developer.wordpress.org/reference/functions/wp_ajax_update_plugin/) might be better reference point for creating a custom plugin update process. There's also the [`Plugin_Upgrader`](https://developer.wordpress.org/reference/classes/plugin_upgrader/) class. For themes there's [`wp_ajax_update_theme`](https://developer.wordpress.org/reference/functions/wp_ajax_update_theme/) for reference and [`Theme_Upgrader`](https://developer.wordpress.org/reference/classes/theme_upgrader/) class. |

329,754 | <p>I've created a block, and I need to save as post_meta a value from an action on the panel.</p>

function yasr_gutenberg_show_in_rest_overall_meta() {

edit:

329,869 | <p><strong>TLDR; How can I run a shortcode with multiple shortcodes inside of it?</strong></p>
<p>I'm trying to run a shortcode with multiple shortcodes inside of it.</p>
<p>I can successfully run a shortcode with one shortcode inside of it with the following code in the theme:</p>
<pre><code>add_shortcode('outside_shortcode', function($attr, $content = null) {
return
'
<section class="example_section">
<div class="container">
<div class="row">

});
add_shortcode('inside_shortcode', function($atts, $content = null) {
$atts = shortcode_atts(
array(
'link' => 'https://link.com',
'image' => 'nameofimage',
), $atts);
return
'
<div class="col-6">
<a href="#!">
<div class="example">
<span class="helper"></span>
<img src="/wp-content/themes/mytheme/assets/images' . $atts['image'] . '.png">

});
</code></pre>
<p>and the following within the texteditor on Wordpress:</p>
<pre><code>[outside_shortcode]
[inside_shortcode link='https://mysite/section1' image='funimage']
[inside_shortcode link='https://mysite/section2' image='coolimage']
[/outside_shortcode]
</code></pre>
<p>However, I want to add a second div within the outside shortcode and add a second shortcode within that. My idea was something like:</p>
<pre><code>add_shortcode('outside_shortcode', function($attr, $content = null) {

Could someone help me with it to avoid loading .css twice and keep full functionality? | You usually don't need to enqueue a child theme's stylesheet. The parent theme does that. This is a bit confusing, so I'll explain.
In most themes, Twenty Seventeen included, the stylesheet is loaded like this:
```
wp_enqueue_style( 'twentyseventeen-style', get_stylesheet_uri() );
```
The trick to understanding what's going on here is understanding what `get_stylesheet_uri()` does. When a regular theme is activated, this function returns the URL to the theme's style.css file. However, when a child theme is activated, the function returns the URL for the *child theme's* style.css file.
This means that when you create a child theme with a style.css file, that file will automatically be enqueued, but the parent theme's won't. So all you need to do in your child theme is enqueue the parent theme's stylesheet:
```
add_action( 'wp_enqueue_scripts', 'child_enqueue_styles', 9 );
function child_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_parent_theme_file_uri( 'style.css' ) );
}
```
Note that I set the priority to `9`. This means that the parent theme's stylesheet will get enqueued before the child theme's, which will be enqueued at the default priority of `10`. |
329,886 | <p>So I want to apply a theme and style the lost password page without the use of a plugin. I don't want it to show the default Wordpress lost password page.

] | So I want to apply a theme and style the lost password page without the use of a plugin. I don't want it to show the default Wordpress lost password page. I managed to style the login form by redirecting the URL to the styled version, but I'm lost as to how I can style the lost password page.
Any ideas?
Thanks! | You usually don't need to enqueue a child theme's stylesheet. The parent theme does that. This is a bit confusing, so I'll explain.
In most themes, Twenty Seventeen included, the stylesheet is loaded like this:
```
wp_enqueue_style( 'twentyseventeen-style', get_stylesheet_uri() );
```
The trick to understanding what's going on here is understanding what `get_stylesheet_uri()` does. When a regular theme is activated, this function returns the URL to the theme's style.css file. However, when a child theme is activated, the function returns the URL for the *child theme's* style.css file.
This means that when you create a child theme with a style.css file, that file will automatically be enqueued, but the parent theme's won't. So all you need to do in your child theme is enqueue the parent theme's stylesheet:
```
add_action( 'wp_enqueue_scripts', 'child_enqueue_styles', 9 );
function child_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_parent_theme_file_uri( 'style.css' ) );
}
```
Note that I set the priority to `9`. This means that the parent theme's stylesheet will get enqueued before the child theme's, which will be enqueued at the default priority of `10`. |

You're de-registering the script on the `init` hook:
```
add_action('init', 'replace_jquery');
```
This hook runs for the back and front end, but the debugger isn't smart enough to know that you're using `! is_admin()` inside the function. Regardless, you should just do what the error recommends and use the `wp_enqueue_scripts` hook:
```
add_action('wp_enqueue_scripts', 'replace_jquery');

The original script will not be enqueued yet on the `init` hook, so attempting to de-register it on that hook won't work, as it will only get re-registered by the time the `wp_enqueue_scripts` hook runs.
Also, the way you're going about this is likely to cause problems, for 2 reasons:
1. You're enqueuing jQuery 3.3.1, but WordPress uses 1.12.4. This means that WordPress itself and the vast majority of plugins are expecting 1.12.4 to be loaded, but 3.3.1 will be loaded. Code written expecting 1.X will not necessarily be compatible with 3.X, which could cause plugins to break.

First of all, you want to perform this action only once and for all sites. So there is no point in using any hooks. Just run the code once and then delete it.
And that code should loop through all sites and set their theme:
```
function switch_all_multisite_themes() {
foreach ( get_sites() as $site ) {
switch_to_blog( $site->blog_id );
switch_theme( 'theme' ); // for example 'twentyten'
restore_current_blog();

] | I have tried to add custom `li` to my wordpress header menu using `functions.php`. Here is my code in `function` file.
```
function register_header_menu() {
register_nav_menu('header-menu',__( 'Header Menu' ));
}
add_action( 'init', 'register_header_menu' );
```
add new element to header menu
```
function add_new_item($items, $args) {
if( $args->theme_location == 'header-menu' ){
$items .= '<li> <a>Show whatever</a></li>';
}
return $items;
}
add_filter('wp_nav_menu_items', 'add_new_item');
```
I'm using below code to add menu into `header.php`
```
wp_nav_menu( array(
'theme_location' => 'header-menu',
'container' => 'ul',
'menu_class' => 'menu',
) ); ?>
```
Menu is visible on header, but my new item is not visible in the menu. How can I fix it? | Default usage of `add_filter` looks like this:
```
add_filter( string $tag, callable $function_to_add, int $priority = 10, int $accepted_args = 1 )
```
As you can see, the default priority is 10 and by default only one param is passed.
In your code you need your filter to get 2 params, because [`wp_nav_menu_items`](https://developer.wordpress.org/reference/hooks/wp_nav_menu_items/) takes 2 params (`$items` and `$args`) and you need both of them in your filter. So you have to pass 2 as number of params, when you add your filter:
```
function add_new_item_to_menu( $items, $args ) {
if ( 'header-menu' == $args->theme_location ) {
$items .= '<li><a>Show whatever</a></li>';
}
return $items;
}
add_filter( 'wp_nav_menu_items', 'add_new_item_to_menu', 10, 2 );

I believe the method that I am approaching this with is correct but I'm missing something that is not allowing the foreach to read the terms to check for the checked boxes. Any insight would be appreciated. | There are two errors in your code.
**First one** is the inconsistency in field names. Here’s your checkbox field:
```
<input type="checkbox" name="competence-<?php echo esc_attr( $term->slug ); ?>" id="competence-<?php echo esc_attr( $term->slug ); ?>" value="<?php echo esc_attr( $term->slug ); ?>" <?php checked( true, is_object_in_term( $user->ID, 'competence', $term ) ); ?> />
```
And here’s the part you’re checking it:
foreach ( $terms as $term ) {
$term = esc\_attr( $\_POST[$term->slug] );
So your field has name `competence-<TERM_SLUG>`, but you’re checking it using only `<TERM_SLUG>`.
It should be:
```
foreach ( $terms as $term ) {
$term = esc_attr( $_POST[ 'competence-' . $term->slug] );
```
**Second problem** is the way you’re setting the terms for object:
```
wp_set_object_terms( $user_id, array( $term ), 'competence', false);
```
Take a look at [wp\_set\_object\_terms docs](https://codex.wordpress.org/Function_Reference/wp_set_object_terms). This is the default call for this function:
```
wp_set_object_terms( $object_id, $terms, $taxonomy, $append );
```
As you can see, the last param is `$append` and it tell if the term should be appended to the existing ones or should it overwrite existing ones. You pass false as the value for that param, so your foreach loop will overwrite existing terms - so only the last one will be saved.
One way to fix it would be like this:
```
$terms = array();
foreach ( $terms as $term ) {
$term = esc_attr( $_POST[ 'competence-' . $term->slug] );
$terms[] = $term;
}
wp_set_object_terms( $user_id, $terms, 'competence', false);

IDs are very much subject to change, and normal activity through the UI can cause problems with any code expecting a specific ID, which makes them fragile.
However, when you see solutions involving a specific ID, you need to keep in mind that the scope of many of these solutions, *especially* on this site, is limited to only the specific problem that the user is asking about.
As a very simple example, a user might ask "How do I print the title of a specific page?", and the solution proposed will be something like:

echo get_the_title( 12 );
```
Where `12` is the ID of a specific page.
Hard-coding the ID `12` is indeed a bad idea, however all this solution is intended to tell the user is that you can output a page title — *given its ID* — using the function `get_the_title()`. Where that ID comes from is a separate issue to the question that was asked.

] | I'm having issues to change the subject of the email sent out when password is changed.
I have managed to change the message by doing this:
```
// Change Email to HTML function
function set_email_html_content_type() {
return 'text/html';
}
// Replace the default password change email
add_filter('password_change_email', 'change_password_mail_message', 10, 3);
function change_password_mail_message( $change_mail, $user, $userdata ) {
// Call Change Email to HTML function
add_filter( 'wp_mail_content_type', 'set_email_html_content_type' );
$message = "<p>Test HTML email</p>";
$change_mail[ 'message' ] = $message;
return $change_mail;
// Remove filter HTML content type
remove_filter( 'wp_mail_content_type', 'set_email_html_content_type' );
}
```
But how do I change the subject which is default as `[Sitename] Notice of Password Change`
Thank you! | The `$change_mail` variable that you're filtering has a `subject` value that you can modify the same way you modified the message:
```
// Replace the default password change email
add_filter('password_change_email', 'change_password_mail_message', 10, 3);
function change_password_mail_message( $change_mail, $user, $userdata ) {
// Call Change Email to HTML function
add_filter( 'wp_mail_content_type', 'set_email_html_content_type' );
$message = "<p>Test HTML email</p>";
$change_mail[ 'message' ] = $message;
$change_mail[ 'subject' ] = 'My new email subject';
return $change_mail;
}
```
(I removed your call to `remove_filter()` because it wouldn't do anything. Nothing after `return` will run.) |

Unserialized `_wp_attachment_metadata` for a "fixed" image:

``` | Running the [`wp media regenerate` command](https://developer.wordpress.org/cli/commands/media/regenerate/) from WP-CLI with the `--only-missing` argument is quite fast (takes about 30 seconds for 4000 images) and rebuilds `_wp_attachment_metadata` correctly:

Plugin: Insert Headers and Footers
<https://pt.wordpress.org/plugins/insert-headers-and-footers/> |
330,251 | <p>I´d like to automatically load three images inside all posts (via single.php), always in the same div (.acf_imgs-centro1). The idea is that the images are uploaded into uploads folder, with the same name as the post, and then they will be displayed inside the post. I can do it using the code bellow, but there is a problem... I have a static title (.imgs_h2) above the images divs, and I want it (the title) to load only since there are any image loaded. I can, for example, have the post and not yet have the image in the folder, so the title will be invisible. No Image, no title.

Plugin: Insert Headers and Footers
<https://pt.wordpress.org/plugins/insert-headers-and-footers/> |
330,346 | <p>I have a function which adds a <code>posts_join</code> and a <code>posts_where</code> to searches in <code>WP_Query</code>. It works fine on a normal, php rendered search page. However i'm also using it for a ajax product search and the additional <code>posts_join</code> and a <code>posts_where</code> don't seem to apply.</p>
<p>Here's the join and where:</p>
<pre><code>function search_by_meta_join($join) {

}
return $join;
}
add_filter('posts_join', 'search_by_meta_join');
function search_by_meta_where($where) {
global $wpdb;
if (is_search()) {
$where = preg_replace(
"/\(\s*{$wpdb->posts}.post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",

);
}
return $where;
}
add_filter('posts_where', 'search_by_meta_where');
</code></pre>
<p>And here's my ajax function:</p>
<pre><code> $args = array(
'posts_per_page' => 12,
'post_type' => 'product',
// 'offset' => filter_var($_GET['offset'], FILTER_SANITIZE_NUMBER_INT),
// 'post_status' => 'publish',
// 'order' => 'ASC',
// 'orderby' => 'title',
);
// Search query
if (isset($_GET['searchQuery']) && $_GET['searchQuery'] != '') {
$args['s'] = filter_var($_GET['searchQuery'], FILTER_SANITIZE_STRING);
}
// Category filter
// if (isset($_GET['category']) && $_GET['category'] !== 0) {
// $args['tax_query'][] = [
// 'taxonomy' => 'product-category',
// 'field' => 'term_id',
// 'terms' => filter_var($_GET['category'], FILTER_SANITIZE_NUMBER_INT),
// ];
// }
$loop = new WP_Query($args);
$products = array();

] | I have a function which adds a `posts_join` and a `posts_where` to searches in `WP_Query`. It works fine on a normal, php rendered search page. However i'm also using it for a ajax product search and the additional `posts_join` and a `posts_where` don't seem to apply.
Here's the join and where:
```
function search_by_meta_join($join) {
global $wpdb;
if (is_search()) {
$join .= " LEFT JOIN {$wpdb->postmeta} pm_ean ON {$wpdb->posts}.ID = pm_ean.post_id AND (pm_ean.meta_key = 'ean') ";
$join .= " LEFT JOIN {$wpdb->postmeta} pm_code ON {$wpdb->posts}.ID = pm_code.post_id AND (pm_code.meta_key = 'product_code') ";
}
return $join;
}
add_filter('posts_join', 'search_by_meta_join');
function search_by_meta_where($where) {
global $wpdb;
if (is_search()) {
$where = preg_replace(
"/\(\s*{$wpdb->posts}.post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",
"({$wpdb->posts}.post_title LIKE $1) OR (pm_ean.meta_value LIKE $1) OR (pm_code.meta_value LIKE $1) ", $where
);
}
return $where;
}
add_filter('posts_where', 'search_by_meta_where');
```
And here's my ajax function:
```
$args = array(
'posts_per_page' => 12,
'post_type' => 'product',
// 'offset' => filter_var($_GET['offset'], FILTER_SANITIZE_NUMBER_INT),
// 'post_status' => 'publish',
// 'order' => 'ASC',
// 'orderby' => 'title',
);
// Search query
if (isset($_GET['searchQuery']) && $_GET['searchQuery'] != '') {
$args['s'] = filter_var($_GET['searchQuery'], FILTER_SANITIZE_STRING);
}
// Category filter
// if (isset($_GET['category']) && $_GET['category'] !== 0) {
// $args['tax_query'][] = [
// 'taxonomy' => 'product-category',
// 'field' => 'term_id',
// 'terms' => filter_var($_GET['category'], FILTER_SANITIZE_NUMBER_INT),
// ];
// }
$loop = new WP_Query($args);
$products = array();
```
As I say it works on a normal search page like so:
```
global $query_string;
wp_parse_str($query_string, $search_query);
$search = new WP_Query($search_query);
```
Am I missing something for the ajax function to use it? | `is_search()` is only true if the *main* query is for the search results. When you create your own query with `new WP_Query`, you're not using the main query. Additionally, AJAX requests do not even have a main query, so functions like `is_search()`, `is_archive()` etc. do not work.
If you want to check if a specific query is a search, you should use the `is_search()` method of the query, like this:
```
$query->is_search();
```
The `posts_join` and `posts_where` filters are applied to all queries, but the callbacks to those filters receive the current query object as an argument, and you can use this to check for any search queries so that you can apply your filter:
```
function search_by_meta_join( $join, $query ) { // <-- Note the additional argument.
global $wpdb;
if ( $query->is_search() ) { // <-- Note that we are checking the current query, not the main query.
}
return $join;
}
add_filter('posts_join', 'search_by_meta_join', 10, 2 ); // <-- Note the '2' which indicates we're accepting 2 arguments.
function search_by_meta_where( $where, $query ) { // <-- Note the additional argument.
global $wpdb;
if ( $query->is_search() ) { // <-- Note that we are checking the current query, not the main query.
}
return $where;
}
add_filter( 'posts_where', 'search_by_meta_where', 10, 2 );// <-- Note the '2' which indicates we're accepting 2 arguments.
```
The same principle applies whenever you're filtering `pre_get_posts` as well. You should always use the query object that's passed to the filter to check these things, otherwise your changes will apply to *all* queries on the search page, including menus, widgets, and secondary queries, not just the specific search query. |
330,356 | <p>I'm trying to understand how datas are being handled when saving to the database in the <strong><em>wpdb</em></strong> class. I have searched for where HTML string datas are handled and found a method in the <code>$this->query()</code> method in the wpdb class where the query string is being stripped and thought it could be there. It's on <a href="https://core.trac.wordpress.org/browser/tags/5.0.3/src/wp-includes/wp-db.php#L1798" rel="nofollow noreferrer">line 1798</a>. The <code>$query</code> string variable is stripped:</p>
<pre><code>$stripped_query = $this->strip_invalid_text_from_query( $query );
</code></pre>
<p>But then I don't understand. I <strong>just can't</strong> find the stripped variable <code>$stripped_query</code> to be used in a query after that. The method is just returning false if it's not exactly like the original?:</p>
<pre><code>if ( $stripped_query !== $query ) {
$this->insert_id = 0;
return false;
}
</code></pre>
<p>Why? Maybe I have misunderstood what <code>strip_invalid_text_from_query()</code> is doing?</p>
<p>Anyway.. As I said, I just wanna find the method that fixes HTML to a database safe string. So that not for example line-breaks destroys the query or so. Does anyone know where that is?</p>

] | I'm trying to understand how datas are being handled when saving to the database in the ***wpdb*** class. I have searched for where HTML string datas are handled and found a method in the `$this->query()` method in the wpdb class where the query string is being stripped and thought it could be there. It's on [line 1798](https://core.trac.wordpress.org/browser/tags/5.0.3/src/wp-includes/wp-db.php#L1798). The `$query` string variable is stripped:
```
$stripped_query = $this->strip_invalid_text_from_query( $query );
```
But then I don't understand. I **just can't** find the stripped variable `$stripped_query` to be used in a query after that. The method is just returning false if it's not exactly like the original?:
```
if ( $stripped_query !== $query ) {
$this->insert_id = 0;
return false;
}
```
Why? Maybe I have misunderstood what `strip_invalid_text_from_query()` is doing?
Anyway.. As I said, I just wanna find the method that fixes HTML to a database safe string. So that not for example line-breaks destroys the query or so. Does anyone know where that is? | `is_search()` is only true if the *main* query is for the search results. When you create your own query with `new WP_Query`, you're not using the main query. Additionally, AJAX requests do not even have a main query, so functions like `is_search()`, `is_archive()` etc. do not work.
If you want to check if a specific query is a search, you should use the `is_search()` method of the query, like this:
```
$query->is_search();
```
The `posts_join` and `posts_where` filters are applied to all queries, but the callbacks to those filters receive the current query object as an argument, and you can use this to check for any search queries so that you can apply your filter:
```
function search_by_meta_join( $join, $query ) { // <-- Note the additional argument.
global $wpdb;
if ( $query->is_search() ) { // <-- Note that we are checking the current query, not the main query.
}
return $join;
}
add_filter('posts_join', 'search_by_meta_join', 10, 2 ); // <-- Note the '2' which indicates we're accepting 2 arguments.
function search_by_meta_where( $where, $query ) { // <-- Note the additional argument.
global $wpdb;
if ( $query->is_search() ) { // <-- Note that we are checking the current query, not the main query.
}
return $where;
}
add_filter( 'posts_where', 'search_by_meta_where', 10, 2 );// <-- Note the '2' which indicates we're accepting 2 arguments.
```
The same principle applies whenever you're filtering `pre_get_posts` as well. You should always use the query object that's passed to the filter to check these things, otherwise your changes will apply to *all* queries on the search page, including menus, widgets, and secondary queries, not just the specific search query. |

330,377 | <p>I wrote a plugin to hit an API and display results on a page. When I was testing, every time I hit "preview", the plugin would hit the API and retrieve the most recent data. Now that the plugin is live, when I navigate to the live page, no calls are being made to the API.</p>
<p>Through research I believe this is a caching issue, since we want real time data, we would like that every time a user navigates to the page, the plugin fires off to the API and the most recent values are returned. </p>
<p>Here is a snippet of my code: </p>
<pre><code>function get_count(){
//get response from api
$request = wp_remote_get('https://myapi.com/count');
if(is_wp_error($request)){
return false;
}
//get the body from the response
$body= json_decode(wp_remote_retrieve_body($request));
//parse the body and get the count attribute
$statistic=($body->payload->count);
return '<div id="value" class="number">'. $statistic . '</div>';
}
add_shortcode('real_time_count','get_count');
</code></pre>
<p>How can I make this execute every time a user navigates to a page that has this shortcode?</p>

] | I wrote a plugin to hit an API and display results on a page. When I was testing, every time I hit "preview", the plugin would hit the API and retrieve the most recent data. Now that the plugin is live, when I navigate to the live page, no calls are being made to the API.
Through research I believe this is a caching issue, since we want real time data, we would like that every time a user navigates to the page, the plugin fires off to the API and the most recent values are returned.
Here is a snippet of my code:
```
function get_count(){
//get response from api
$request = wp_remote_get('https://myapi.com/count');
if(is_wp_error($request)){
return false;
}
//get the body from the response
$body= json_decode(wp_remote_retrieve_body($request));
//parse the body and get the count attribute
$statistic=($body->payload->count);
return '<div id="value" class="number">'. $statistic . '</div>';
}
add_shortcode('real_time_count','get_count');
```
How can I make this execute every time a user navigates to a page that has this shortcode? | It is possible. For that we will use 4 hooks (actions): show\_user\_profile, edit\_user\_profile, personal\_options\_update, edit\_user\_profile\_update.
Here is the example how to add extra field to user in WordPress.
Adding user info fields function
```
add_action( 'show_user_profile', 'extra_user_profile_fields', 10, 1 );
add_action( 'edit_user_profile', 'extra_user_profile_fields', 10, 1 );
function extra_user_profile_fields( $user ) { ?>
<h3><?php _e("Extra profile information", "blank"); ?></h3>
<table class="form-table">
<tr>
<th><label for="user_img_path_image"><?php _e("Image path"); ?></label></th>
<td>
<input type="text" name="user_img_path_image" id="user_img_path_image" value="<?php echo esc_attr( get_the_author_meta( 'user_img_path_image', $user->ID ) ); ?>" class="regular-text" /><br />
<span class="description"><?php _e("Path to country image."); ?></span>
</td>
</tr>
<tr>
<th><label for="user_country_field"><?php _e("Country field"); ?></label></th>
<td>
<input type="text" name="user_country_field" id="user_country_field" value="<?php echo esc_attr( get_the_author_meta( 'user_country_field', $user->ID ) ); ?>" class="regular-text" /><br />
<span class="description"><?php _e(""); ?></span>
</td>
</tr>
</table>
<?php }
```
Here is the extra code for save and edit function
```
add_action( 'personal_options_update', 'save_extra_user_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_user_profile_fields' );
function save_extra_user_profile_fields( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) ) {
return false;
}
update_user_meta( $user_id, 'user_img_path_image', $_POST['user_img_path_image'] );
update_user_meta( $user_id, 'user_country_field', $_POST['user_country_field'] );
}
// end - Add user info fields
```
Just copy and paste this code in your plugin or function.php and you must see new 2 fields in Wordpress backend user editing/adding page.
For extracting your date in frontend use this code:
```
$user_facebook_id_acc = get_the_author_meta( 'user_facebook_id_acc', $current_user_data->ID );

I've put together a [procedure](https://securitydawg.com/recovering-from-a-hacked-wordpress-site/) I use to clean up a site. It takes a while, but can be done. There are other similar resources available via your favorite search engine. |

Is there a way to drive this feature programmatically, eg. by uploading media and setting an option with `wp cli`? | Use wp-cli commands `wp media import` and `wp option update`.
`wp media import <file>` : Creates attachments from local files or URLs.
`wp option update <key>` : Updates an option value.
**Image from theme folder** :
```
$ wp media import "$(wp theme path)/theme/assets/images/logo.png" --porcelain | wp option update site_icon
```
**Image from url** :
```
$ wp media import "https://source.unsplash.com/random/512x512" --porcelain | wp option update site_icon

The flag [--porcelain] output just the new attachment ID.

I'm aware of the various hooks and filters listed in the codex, but I have a use case which requires a simple line of html be present across the whole site and after several hours of research I'm no further forward. | If you look the **wp-login.php** file, you will see a hook **login\_header**. So you add any custom content above the login form. Here is the example:
```
add_action( 'login_header', 'wpse330527_add_html_content' );
function wpse330527_add_html_content() {
?>
ENTER YOUR HTML CODE
<?php
}
```
You will add the code into functions.php file of your active theme. |
